Zodiac Sign Finder
Free Zodiac Sign Finder for astrology & numerology. Free online tool with accurate results using verified formulas.
Formula
Zodiac Sign = Position of the Sun at birth date along the ecliptic
Enter your full birth date (day, month, year) and this finder returns your Sun sign, element (Fire/Earth/Air/Water), modality (Cardinal/Fixed/Mutable), ruling planet, and compatible signs. Unlike a basic sign lookup, it also shows which zodiac house the Sun enters at the cusp dates and notes if your birthday falls on a cusp (within 2 days of a sign change).

Frequently Asked Questions
What are the 12 zodiac signs and their dates?
The 12 zodiac signs and their approximate date ranges are: Aries (March 21 to April 19), Taurus (April 20 to May 20), Gemini (May 21 to June 20), Cancer (June 21 to July 22), Leo (July 23 to August 22), Virgo (August 23 to September 22), Libra (September 23 to October 22), Scorpio (October 23 to November 21), Sagittarius (November 22 to December 21), and Capricorn (December 22 to January 19), Aquarius (January 20 to February 18), and Pisces (February 19 to March 20). These dates can shift by a day or two each year because the zodiac is based on the Sun's position relative to constellations, and the calendar does not perfectly align with the solar year. Cusp dates (birthdays near the transition) may show traits of both signs.
How does zodiac compatibility work?
Zodiac compatibility is based on how the elements and qualities of different signs interact with each other. Signs of the same element (for example, two Fire signs) generally understand each other well and share similar values and energy. Complementary elements also pair well: Fire and Air signs energize each other, while Earth and Water signs ground and nurture each other. Opposite signs on the zodiac wheel (like Aries and Libra, or Taurus and Scorpio) often experience strong attraction and can balance each other despite differences. Signs that are square to each other (90 degrees apart, like Aries and Cancer) may experience tension but also dynamic growth. However, full compatibility requires comparing complete birth charts, not just Sun signs, as Moon signs, Venus signs, and rising signs all play important roles in relationship dynamics.
